[vtkusers] delaunay2D and closed polygons (first point repeated as last)

[sebastien MARAUX]

Do you use it for contrained triangulations ?

if I do so, the triangle linked with the last line of each 
contour is taken off of the final object, leaving a hole 
in shape of triangle in the final object for each polygon.

  Seb,
   
  I use Delaunay2D without closed polygons.

  Is it normal that Delaunay2D needs closed polygons (i.e.
  first point is repeated as last in polygons definition) for 
  constraints ? 
   
  As VTK defines a VTK_POLYGON (check user's guide 
  p.358) I would expect classes to handle polygons without 
  repeating last point.

  Could someone familiar with delaunay2D code check this?

  Thanks

  Seb
